Hi! I had to remove a XenServer host (the only one) from Cloudstack, removed it via GUI, worked well.
Now I added the replacement machine, and tried to fire up an instance. But I got the message "Unable to locate datastore with id 1". In the database, the storage_pool table contained two entries, the old id 1 and the current id 2. I removed the host (and then replaced the EXT storage with a LVM storage because I misconfigured it), and added it again. Now I have three entries in the database, and creating an instance still fails. The database now looks like this: mysql> select * from storage_pool; +----+-----------------------------+--------------------------------------+-----------+------+----------------+--------+------------+------------+----------------+--------------+-----------+------+---------------------+---------------------+-------------+-------------+-----------------------+-------+------------+---------+---------------+ | id | name | uuid | pool_type | port | data_center_id | pod_id | cluster_id | used_bytes | capacity_bytes | host_address | user_info | path | created | removed | update_time | status | storage_provider_name | scope | hypervisor | managed | capacity_iops | +----+-----------------------------+--------------------------------------+-----------+------+----------------+--------+------------+------------+----------------+--------------+-----------+------+---------------------+---------------------+-------------+-------------+-----------------------+-------+------------+---------+---------------+ | 1 | esc-compute01 Local Storage | NULL | LVM | 0 | 1 | 1 | NULL | 4194304 | 1190452527104 | 10.8.0.65 | NULL | lvm | 2014-08-08 14:37:25 | 2014-08-18 08:33:43 | NULL | Maintenance | DefaultPrimary | HOST | NULL | 0 | NULL | | 2 | esc-compute01 Local Storage | NULL | EXT | 0 | 1 | 1 | NULL | 6161043456 | 1171772600320 | 10.8.0.66 | NULL | ext | 2014-08-27 15:53:58 | 2014-08-28 15:50:41 | NULL | Maintenance | DefaultPrimary | HOST | NULL | 0 | NULL | | 3 | esc-compute01 Local Storage | c38b4fa3-4bd4-05a3-4a11-e5e0f15fb9f5 | LVM | 0 | 1 | 1 | 1 | 4194304 | 1190452527104 | 10.8.0.66 | NULL | lvm | 2014-08-28 15:52:14 | NULL | NULL | Up | DefaultPrimary | HOST | NULL | 0 | NULL | +----+-----------------------------+--------------------------------------+-----------+------+----------------+--------+------------+------------+----------------+--------------+-----------+------+---------------------+---------------------+-------------+-------------+-----------------------+-------+------------+---------+---------------+ 3 rows in set (0.00 sec) In the GUI, I can only see one Primary Storage (the current "real" one, obviously ID 3). How can I fix my Cloudstack? As there are no instances yet, I could reinstall, but I'd like to understand what's going on... Thanks Martin Emrich
